Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989812, here are decompositions:

29 + 989783 = 989812
59 + 989753 = 989812
149 + 989663 = 989812
233 + 989579 = 989812
251 + 989561 = 989812
389 + 989423 = 989812
401 + 989411 = 989812
431 + 989381 = 989812

Showing the first eight; more decompositions exist.
